Diffuse large B-cell lymphomas (DLBCLs) are a biologically heterogeneous group in which various gene alterations have been reported. The aim of this study was to investigate the frequency and prognostic impact of BCL2, BCL6, and MYC rearrangements in cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab (R-CHOP)-treated DLBCL cases. ⋯ Analysis of MYC gene rearrangement along with BCL2 and BCL6 is critical in identifying high-risk patients with poor prognosis.

Atypical teratoid rhabdoid tumor (ATRT) is a rare central nervous system malignancy with a poor prognosis that affects mostly young children. Although radiotherapy (RT) historically has been delayed in patients aged <3 years, emerging evidence suggests a role for RT to achieve long-term survivorship. Clinical features and age-dependent trends of RT use were evaluated for patients with ATRT. ⋯ The current results indicated that RT may offer a significant survival benefit for patients with ATRT and that patients aged ≤3 years may derive more benefit from initial RT compared with older children. The authors concluded that prospective clinical trials are needed to examine the role of RT in the initial management of ATRT in patients aged <3 years.

Randomized Controlled Trial Multicenter Study
A double-blind, randomized, placebo-controlled, phase 2 study of maintenance enzastaurin with 5-fluorouracil/leucovorin plus bevacizumab after first-line therapy for metastatic colorectal cancer.
Enzastaurin and bevacizumab have demonstrated synergistic antitumor effects and, in phase 1 studies, the combination was well tolerated. This phase 2 study assessed enzastaurin with 5-fluorouracil/leucovorin plus bevacizumab as maintenance therapy for metastatic colorectal cancer (MCRC). ⋯ Enzastaurin combined with bevacizumab-based therapy is tolerable, but does not improve PFS during maintenance therapy in patients with MCRC compared with bevacizumab-based therapy alone.

The authors tested whether an educational video on the goals of care in advanced cancer (life-prolonging care, basic care, or comfort care) helped patients understand these goals and had an impact on their preferences for resuscitation. ⋯ Patients with advanced cancer did not change care preferences after viewing the video, but fewer wanted CPR or ventilation. Documented code status was inconsistent with patient preferences. Patients were more knowledgeable after the video, reported that the video was acceptable, and said they would recommend it to others. The current results indicated that this type of video may enable patients to visualize "goals of care," enriching patient understanding of worsening health states and better informing decision making.

Comparative Study
Improved survival for BRCA2-associated serous ovarian cancer compared with both BRCA-negative and BRCA1-associated serous ovarian cancer.
Multiple observational studies have suggested that breast cancer gene (BRCA)-associated ovarian cancers have improved survival compared with BRCA-negative ovarian cancers. However, most of those studies combined BRCA1 and BRCA2 patients or evaluated only BRCA1 patients. The objective of the current study was to examine whether BRCA1-associated and BRCA2-associated ovarian cancers were associated with different outcomes. ⋯ The current data suggests that BRCA2 mutations confer an overall survival advantage compared with either being BRCA-negative or having a BRCA1 mutation in high-grade serous ovarian cancer. This finding may have important implications for clinical trial design.
